How to repeat a song on Spotify iOS app

Hello all! I hope you are all doing well!

I have a question about songs, and the Spotify app. Last night, I had some writing to do, and I wanted a song to repeat. But when I played the song, and tried to find the repeat button, it was no use. I couldn’t find the button. Which led to me having to get the previous button every time it ended. My question is, how do you get songs to repeat in the Spotify iOS app? Thank you in advance! :-)
